Sex crimes include acts considered sexual abuse or intolerable behavior considered inappropriate by social norms. The law prohibits certain sexual acts, despite the express consent of both parties. Sex laws vary from region to region and may evolve over time. Furthermore, sexual acts prohibited by law in a proscribed jurisdiction are defined as sex crimes. Rape, or forced sexual intercourse without the consent of both parties, can involve physical violence, threats, and verbal abuse to intimidate and violate a person's body. Rape is considered a federal crime in the Western world. A perpetrator committed in the act of forced intercourse is known as a rapist. According to the American Medical Association, rape victims tend to avoid reporting a violation, often out of shame or guilt. The U.S. Bureau of Justice Statistics reports that ninety-one percent of all rape victims in the United States are women, nine percent are men, and ninety-nine percent of perpetrators are men.
